ANCHOR-ROD EYE.

Specification of Letters Patent.

Patented Mar. 29, 1921.

Application filed February 21,1918. Serial No. 218,574.

To all whom it may cance I Be it known that I, All we B. CHANcn, acitizen of the United S ates of America, residing at Centralia, in hecounty of'Boone and State of Missouri, have invented a new and usefulAnchor-Rod Eye, of which the following is a specification, referencebeing had to the accompanying drawings, illustrating the preferred formof the invention.

My invention relates to eyes for anchor rods or other rods or membersused in conjunction with strain members such as wires, strands, ropes,or stranded cables.

The principal objects of my invention are, to provide an improved eyefor rods or other members, of the character substantially as herein setforth; to provide an improved construction in such devices embodyingboth an eye and a thimble for a strain member; and to provide in suchanchor rod eyes a reinforced construction enabling the rod to bevigorously driven into hard earth of various characters without damageto the eye. Other objects will be apparent from the followingspecification.

In the accompanying drawings, illustrating the preferred form of myinvention, Figure 1 is a side elevation of an anchor rod provided withthe improved eye of my invention; Fig. 2 is a side elevation of the rodand eye of Fig. 1, looking in the direction of arrow A with respect toFig. 1; Fig. 3 is a top end view of Fig. 1, showing only the anchor rodeye construction; and Fig. 4 is a side elevation of my improved anchorrod eye, taken the same as Fig. 2, showing a strain member attached tothe improved eye structure.

Like characters refer to like parts in the several figures.

. In the drawings, 1 represents an anchor rod, preferably provided witha pointed portion 2 adapted to be driven into the earth and to cooperatewith a suitable anchor plate, not shown, for guying telephone,telegraph, or other poles, smoke stacks, etc. The member 1 may, incertain instances, be a part of other devices besides anchor rods.

The top end of the rod 1 is provided with my improved eye structure,preferably as shown although it may be varied to givethe desired resultsand to suit the requirements. The eye proper is shown at 3, the thimbleportion at 4, and the reinforced portion to permit driving of the rodwithout damage to the eye 3 or thimble portion 4 is shown at 5. I havepreferably shown the opening 3 of the eye to be circular, transversely,but it may in certain instances be made in other shapes. The thimbleportion 4 is preferably semlclrcular in longitudinal extent, as shown 1nFig. 2, and concave in cross-section, preferably substantiallysemicircular. In use, the strain member 6 extends through the opemng 3of the eye and lies in the concave semicircular thimble portion 4 asshown in Fig. 4, the strain member 6 being held in association with thethimble portion 4 by a suitable clamp 7 or other suitable means. Thus mythimble portion 4 entirely takes the place of the separate thimbleheretofore used in connection with anchor rod eyes and otherstrand-holding devices, and provides a large smooth bend for the strand6 to pull against which protects the strand 6 from injury which itusually receives when pulling against the ordinary small eye without athimble. The strain member 6 may be a single strand,-or a twisted orstranded rope or cable, or, in fact, any suitable strain member.

The whole eye structure 3 4 5 is preferably drop-forged to shape frommaterial upset from the end of the rod 1, in the construction shown, butit may be made in other manners without departing from my invention.Drop-forging is a very cheap and substantial method of making myimproved eye structure.

The design of the anchor rod eye illustrated in this application, formsthe subj ectmatter of my United States Design Patent No. 56,273, whichissued on Sept. 14, 1920, for design for anchor rod eyes.

I do not wish to limit this invention to the exact details ofconstruction herein set forth, as various modifications thereof may bemade or utilized without departing from the scope of the appendedclaims.

What I claim as my invention is:

1. An anchor rod having an integral end portion thereof formed toprovide an eye and a substantially semicircular groove extending throughthe eye and projecting from opposite sides thereof to form a curvedbearing of increased perimeter for a strain member, the said groovehaving a substantially semicircular cross-section, the extreme end ofthe rod member being thickened to provide a reinforced driving portion.

2. An anchor rod having an integral end: As inventor of the foregoing Ihereunto portion thereof formed to provide an eye subscribe my name,this 16 day of Febru- 10 and aourved groove egtending through ghe ary,1918.

e e and 1O]80tin rom opposite si es thereof to form a ourved bearing ofin- ALBERT CHANCE creased perimeter for a strain member, the Witnesses:

ened to provide a reinforced driving portion. I. L. TRAUGHBEB.
